Problem with inode reclaim is that it puts inodes into I_FREEING stateand then continues to gather more, during which it may iput,invalidate_mapping_pages, be preempted, etc. Holding these inodes inI_FREEING can cause pauses.

After the inode scalability work, there is not a big reason to batchup inodes to reclaim them, so dispose them as they are found from theLRU.
